# Firefox Adds Full AI Feature Block Soon
Mozilla is rolling out a powerful new "Block AI enhancements" toggle in Firefox 148, allowing users to completely disable all current and future generative AI features with a single switch, addressing widespread privacy concerns amid the browser's growing AI integrations.[3][5] This user-centric update, launching on February 24, empowers Firefox fans to browse without any AI interference while keeping optional tools available for those who want them.[1][4]
Mozilla's Bold Move: Introducing the AI Kill Switch
In a direct response to community backlash over AI creep in browsers, Mozilla has confirmed a master AI kill switch that goes beyond opt-in controls, fully blocking AI components when activated.[2][3] Firefox head Ajit Varma emphasized that the new AI controls section in desktop settings provides "a single place to block current and future generative AI features," ensuring preferences persist across updates without pop-ups or reminders.[3][5] This feature builds on earlier promises from new CEO Anthony Enzor-DeMeo, who in late 2025 assured users of a "real kill switch" in early 2026 to maintain Firefox's core value of user control.[1][2]
The toggle effectively removes AI functionalities entirely, distinguishing it from mere opt-in options by preventing re-enablement until manually toggled off.[2] Mozilla's official blog highlights this as a commitment to choice, letting users tailor their experience amid an AI-saturated web landscape.[5]
What AI Features Can You Block in Firefox 148?
Firefox 148's AI controls panel lets users manage or disable five key AI-powered features individually, offering granular control for mixed preferences.[3][4][5]
- Translations: Browse in your preferred language with AI-driven page translation.[5]
- Alt text in PDFs: Automatically generates accessibility descriptions for images in PDF documents.[4][5]
- AI-enhanced tab grouping: Suggests related tabs and auto-generates group names for better organization.[3][5]
- Link previews: Displays key points from links before clicking, powered by generative AI.[4][5]
- Sidebar AI chatbot: Quick access to services like Anthropic Claude, ChatGPT, Microsoft Copilot, Google Gemini, and Le Chat Mistral.[3][5]
Enabling the full Block AI enhancements toggle disables all of these at once, blocking even upcoming features and ensuring a pure, AI-free browsing experience.[3][9]
Why Now? User Feedback Drives Firefox's AI Reversal
Mozilla's pivot stems from vocal user opposition on platforms like Reddit and Mozilla Connect, where AI additions like sidebar chatbots and Perplexity AI search sparked fears of Firefox losing its privacy-first identity.[1][6][8] New CEO Enzor-DeMeo, appointed in December 2025, promised to evolve Firefox into a "modern AI browser" but stressed optionality, stating "AI should always be a choice — something people can easily turn off."[1][4]
This update arrives as competitors like Google Chrome and Microsoft Edge push AI aggressively with Gemini and Copilot, potentially inspiring them to adopt similar blocks.[1] Amid browser market shifts from players like Perplexity and Arc, Mozilla positions itself as the transparent choice, with President Mark Surman building alliances for trustworthy AI.[4]
Firefox's Future: Balancing AI Innovation and User Choice
While the AI kill switch reassures skeptics, Mozilla continues developing opt-in features like the upcoming AI Window for chatbot access, available via waitlist.[1] Firefox 148's rollout on February 24 marks a key moment, blending innovation with control to retain its loyal base.[3][5][9] Developers like Jake Archibald have confirmed the feature's permanence, aiming to make Firefox "work for everyone without losing its core values."[2]
